If you are on a tight budget, the options above aren't cheap and a T56 is going to cost even more.

Cheap options:

-Use the Saginaw 3 speed you already have. They are actually a decently strong transmission but most people cast them aside because they want the extra gear. Converted to floor shift, it could be a fun setup. With the 3.73 gears out back I bet it would run pretty good.

-Use a Saginaw 4 speed. This is basically a 3 speed with 4 gears in it, and the downside to that is that the gears are thinner and not as strong. These are cheap to buy because they cant handle as much as the more expensive 4 speeds. It's a gamble whether it would live behind your motor but if you don't get to crazy with side stepping the clutch and power shifting it should live. Some claim to abuse them and they last and some say they've broken tons of them.

I had one in my car.. 4 speed saggy.. same one is actually going into my truck... went through 2 motors.. handled everything.. i abused mine.. raced everywhere.. but at the same time i had decent gears... and a shorter tire, and the thing never really did hook up till 3rd.
